In this paper two direct ac-to-dc power electronics converter topologies are proposed for efficient and optimum energy harvesting from low voltage microgenerators. The conventional power electronics converters used for such applications have two stages, a diode bridge rectifier at the front end followed...
Three pulse-width modulation (PWM) control schemes for a single-phase power-factor-correction (PFC) AC/DC converter are presented to improve the power qual... BR Lin,HH Lu - 《IEEE Transactions on Aerospace & Electronic Systems》 被引量: 97发表: 2000年 New topologies of active input curren...
Fly-back topology is widely used in AC-DC converter design for its many irreplaceable outstanding characteristics over the other isolated topologies. In the previous AC-DC converter solution, usually, an opto-coupler is added on secondary feedback circuitry for transforming the output signal into lig...
The second stage, the DC-to-AC converter, generates a high-frequency voltage that generally drives a transformer at 20 kHz or above. DC-to-AC converter topologies fall into three groups: hard-switched, soft-switched, and resonant. High-power DC power supplies: there's no need to risk the...
